A liftgate force control assembly (20) adjusts the force required to move a liftgate (12) that is pivotally secured to a motor vehicle (10) using a hinge (14). The liftgate force control assembly includes a track (42) that is fixedly secured to the motor vehicle. A follower (46) is movably secured to the track. A strut (34, 36) has a movable end (26, 28) and a secured end (30, 32). The secured end (30, 32) is pivotally secured to the liftgate (12) and the movable end (26, 28) is pivotally secured to the follower (46). The strut (34, 36) defines a moment with respect to the hinge that secures the liftgate to the motor vehicle. A motor (50) is connected to the follower (46) to move the follower (46) along the track (42) changing the moment of the strut such that the force required to move the liftgate (12) changes as the moment changes.

L'invention concerne un ensemble de contrôle de force de déplacement de hayon (20), pour le réglage de la force de déplacement du hayon (12), monté pivotant sur un véhicule à moteur (10) par le biais d'une charnière (14). L'ensemble comprend un rail (42) fixé au véhicule. Un élément transporteur/glissière (46) est relié mobile à ce rail. Un montant (34, 36) comporte une extrémité mobile (26, 28) et une extrémité fixe (30, 32), laquelle est reliée pivotante au hayon (12), tandis que l'extrémité mobile (26, 28) est reliée pivotante à l'élément transporteur/glissière (46). Le montant (34, 36) définit un moment par rapport à la charnière, permettant de fixer le hayon au véhicule. Un moteur (50) est relié à l'élément transporteur/glissière (46), pour déplacer celui-ci (46) le long du rail (42) et modifier le moment du montant, ce qui permet de modifier la force nécessaire au déplacement du hayon (12), en fonction de la variation dudit moment.
